Objective: In order to observe the kinds and intensity of the working noise of Yansan Petrochemical Co. and the effects caused by the working noise on the workers' vestibular and auditory function. Method :The intensity and frequency of the working noise were recorded by exactolnoisemeter in the workshop. One hundred and seventeen workers were tested in routine pure-tone tested method. The SPVN and ABR were tested within fifty-one workers of all. Result:The working noise of Yansan Petrochemical Co. belongs to the broad band and steady noise. The intensity of the working noise were during 85.7~104.0 dB (A) and the main frequency were during 1~8 kHz. About 59 percent workers who exposed to the working noise had hearing loss. The most hearing-loss were in the high frequency. The hearing-loss of speech frequency were slight. Workers who have more six years standing have obviously increased hearing-loss than the workers who have less five years standing. There were significant differences the ABR thresholds and wave-interval between the tested and controlled groups. The SPVN and CP were abnormal in more than 17.4 percent workers with hearing loss. Conclusion: The working noise of Yansan Petrochemical Co. belongs to the broad band and steady noise. Working noise can lead to workers' hearing loss of certain degrees who exposed in the noise for a long time. Obvious correlation was not defined between the hearing-loss and the abnormal vestibular response group.

Objective To explore the correlation between histological chorioamnionitis (HC) and brain injury in preterm infants. Methods Three hundred and forty-seven cases of infants at the gestational age of 28-31 weeks who were admitted to the neonatology department of our hospital were analyzed retrospectively. They were divided into the HC group and the control group according to the pathological examination. Moreover, HC group was divided into FV group and non-FV group according to the pathological findings of fetal vasculitis (FV). Based on the findings of periodical ultrasonography, the incidences of periventricular leukomalacia (PVL), periventricular-intraventricular hemorrhage (PVH-IVH), and the PVL+PVH-IVH were compared among groups. Results The incidences of PVL in the HC group and the control group were 17.9% and 10.3%respectively. The incidences of PVL+PVH-IVH in the two groups were 5.5%and 1.48%respectively, and the difference between two groups was signiifcant (P<0.05). The incidences of PVH-IVH in the two groups were 28.9%and 26.2%respectively, and the difference between two groups was not signiifcant (P>0.05). In the HC group, the incidences of PVL in FV group and non-FV group were 28.1%and 9.87%respectively, and the difference between two groups was signiifcant (P<0.05). The incidences of PVH-IVH in FV group and non-FV group were 34.3%and 24.7%respectively, and the difference between two groups was not signiifcant (P>0.05). The incidences of PVL+PVH-IVH in FV group and non-FV group were 7.81%and 3.70%respectively, and the difference between the two groups was not have signiifcant (P>0.05). Conclusions HC may increase the ncidences of PVL and PVL+PVH-IVH in the preterm infants, while its effect is minimal on PVH-IVH. FV could increase the incidence of brain injury in preterm infants.
7.Noninvasive diagnosis of esophageal varices in liver cirrhosis
Journal of Clinical Hepatology 2020;36(8):1842-1846
Esophageal varices (EV) are the most common complication in patients with liver cirrhosis. Although achievements have been made in the development of endoscopy and other hemostatic techniques, the 6-week mortality rate is still as high as 16%-26% in patients with esophageal variceal bleeding, and therefore, early diagnosis of EV, especially high-risk EV, is of great importance. At present, gastroscopy is the gold standard for the diagnosis of EV, but its clinical application is limited by invasiveness, high cost, and patient discomfort. In recent years, several noninvasive tests have been proposed for the diagnosis of EV, among which the original Baveno VI criteria and its expanded criteria are the most commonly used ones. This article summarizes and reviews the advances in serological marker, ultrasound, CT, MRI, elastography, capsule endoscopy, and ultrathin endoscopy in the noninvasive diagnosis of EV and emphasizes the development of simple noninvasive technology, so as to provide help for the early diagnosis of EV.

Objective:To evaluate the role of long-chain non-coding RNA-lung cancer metastasis-related transcript 1/microRNA-145/Bcl-2 and adenovirus E1B19k Da interacting protein 3 (Lnc-MALAT1/miRNA-145/BNIP3) signaling pathway in sufentanil preconditioning-induced cardioprotection in rats.Methods:Rat H9C2 cells were inoculated in 6-well culture plates or flasks at a density of 1×10 6 cells/ml and divided into 5 groups ( n=30 each) using a random number table method: control group (group C), hypoxia-reoxygenation (H/R) group, sufentanil preconditioning group (S group), eukaryotic expression vector pcDNA3.0 group (pcDNA group) and pcDNA-MALAT1 group (MALAT1 group). Cells were incubated with 10 μmol/L sufentanil for 2 h, and then the H/R injury model was established in group S. In pcDNA group and MALAT1 group, cells were transfected with pcDNA3.0 and pcDNA-MALAT1, respectively, and then incubated with 10 μmol/L sufentanil for 2 h starting from 24 h after transfection, and then the H/R injury model was established.At 2 h after reoxygenation, the expression of Lnc-MALAT1, miRNA-145 and BNIP3 mRNA was detected by real-time polymerase chain reaction, the cell survival rate was detected by CCK-8, the apoptosis rate was detected by flow cytometry, the malondialdehyde (MDA) and superoxide dismutase (SOD) levels and amount of lactic dehydrogenase (LDH) released were detected, and the expression of Bcl-2, Bax and cleaved-caspase-3 was detected by Western blot. Results:Compared with group C, the survival rate was significantly decreased, apoptosis rate was increased, the MDA level and amount of LDH released were increased, SOD levels were decreased, the expression of LncRNA-MALAT1, BNIP3 mRNA, Bax, and cleaved-caspase-3 was up-regulated, and miRNA-145 and Bcl-2 expression was down-regulated in the other four groups ( P<0.05). Compared with group H/R, the cell survival rate was significantly increased, apoptosis rate was decreased, the MDA level and amount of LDH released were decreased, SOD levels were increased, the expression of LncRNA-MALAT1, BNIP3 mRNA, Bax, and cleaved-caspase-3 was down-regulated, and miRNA-145 and Bcl-2 expression was up-regulated in S and pcDNA groups ( P<0.05).

Background::The CHA 2DS 2–VASc score was initially applied to stratify stroke risk in patients with atrial fibrillation (AF) and was found to be effective in predicting all-cause mortality outcomes. To date, it is still unclear whether circulating long non-coding RNAs (lncRNAs) as emerging biomarkers, can improve the predictive power of the CHA 2DS 2–VASc score in stroke and all-cause mortality. Methods::Candidate lncRNAs were screened by searching the literature and analyzing previous RNA sequencing results. After preliminary verification in 29 patients with AF, the final selected lncRNAs were evaluated by Cox proportional hazards regression in 192 patients to determine whether their relative expression levels were associated with stroke and all-cause mortality. The c-statistic, net reclassification improvement (NRI), and integrated discrimination improvement of the patients were calculated to evaluate the discrimination and reclassification power for stroke and all-cause mortality when adding lncRNA expression levels to the CHA 2DS 2–VASc score model. Results::Five plasma lncRNAs associated with stroke and all-cause mortality in AF patients were selected in our screening process. Patients with elevated H19 levels were found to have a higher risk of stroke (hazard ratio [HR] 3.264, 95% confidence interval [CI]: 1.364–7.813, P = 0.008). Adding the H19 expression level to the CHA 2DS 2–VASc score significantly improved the discrimination and reclassification power of the CHA 2DS 2–VASc score for stroke in AF patients. In addition, the H19 level showed a marginally significant association with all-cause mortality (HR 2.263, 95% CI: 0.889–5.760, P = 0.087), although it appeared to have no significant improvement for the CHA 2DS 2–VASc model for predicting all-cause mortality. Conclusions::Plasma expression of H19 was associated with stroke risk in AF patients and improved the discriminatory power of the CHA 2DS 2–VASc score. Therefore, lncRNA H19 served as an emerging non-invasive biomarker for stroke risk prediction in patients with AF.
